An object put in motion wants to stay in motion, right? If you are peddling a bicycle from a stop, you have to really stand on the pedal to get moving, then when you are moving it gets easier. The same with a car, it takes more effort to start moving which takes gas really dumping into the engine.

When you are coming up to a stop on your bike, if you kept peddling all the way to the finish line you will be expending energy all the way until you stop peddling. So you coast to a stop so your legs can rest. That is the same as an engine, it can not work to maintain speed and instead allow itself to slow down.
